  1. 1. Development of visible spectroscopic techniques for applications in plasma diagnostics

    Författare :Katarzyna Jakubowska; Elisabeth Rachlew-Källne; Per Brusell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : In this thesis visible spectroscopy is developed and used for two applications. Studies of motional Stark effect spectra for diagnosing the current distribution in the fusion plasmas with two different spectroscopic diagnostic systems: ratiometry and interferometry. LÄS MER

  3. 2. Diagnostics for advanced fusion plasma scenarios

    Författare :Mattias Kuldkepp; Elisabeth Rachlew-Källne; Fritz Wagner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MSE; PEM; mirror evolution; fusion; diagnostics; plasma spectroscopy; reversed field pinch; spherical tokamak; intelligent shell; PPCD; MAST; ITER; Molecular physics; Molekylfysik;

    Sammanfattning : Over the past decade, fusion research has showed the potential of being a main candidate for energy production for future generations. Further advances in improved fusion performance are therefore vital. This thesis focuses on advanced fusion plasma scenarios and their diagnostic requirements. LÄS MER

  4. 3. Synchrotron radiation spectroscopy of molecular dynamics beyond the valence shell

    Författare :Emilio Melero Garcia; Elisabeth Rachlew Källne; Nora Berrah; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular physics; Molekylfysik;

    Sammanfattning : This thesis presents experimental results on molecular spectroscopy of gas phase molecules using synchrotron radiation. It deals mainly with dynamical processes following resonant excitation of electrons from core and inner-valence shells of the following systems H2O, H2, SF6 and CD4. LÄS MER

  5. 4. Visible spectroscopic diagnostics : application and development in fusion plasmas

    Författare :Sheena Menmuir; Professor Elisabeth Rachlew-Källne; Lorella Carraro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; visible spectroscopy; fusion; Doppler shift; Doppler broadening; Plasma physics with fusion; Plasmafysik med fusion;

    Sammanfattning : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. LÄS MER

  7. 5. Visible spectroscopy as a sensitive diagnostic tool for fusion plasmas

    Författare :Sheena Menmuir; Elisabeth Rachlew-Källne; Mats Larsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular physics; Molekylfysik;

    Sammanfattning : To further the understanding and knowledge about fusion plasmas and their behaviour during different conditions, it is important to be able to collect information about the plasma and the processes occurring within it. Visible spectroscopy, or the study of the visible wavelength light emitted by the plasma, is a useful tool in this search for knowledge. LÄS MER
